Simply having a notification on login that the account was locked, why, and means of unlocking it — unless there was proof of abuse - to me would have been the appropriate response. Not to mention you unilaterally edited username I had to remove spaces, which wasn’t blocked when I created username.

Basically, you’re not acknowledging both your error messages/notifications have repeatedly been problematic— or that banning users who used the system as designed is wrong.
